A rod 32 is operatively connected at the lower end to the needle valveof the carbureter 10 and is loosely passed through the bushing 27. Theupper end of the rod is equipped with a yoke 33 which is'held yieldablyagainst the head 28 by means of a spring 34E which surrounds the rod 32and is con fined under tension between the inner .end of the bushing 27and a collar 35 which is fixed to the rod. The spring permits of rotarymovement of the rod 32 but resists longitudinal movement of the rod tosuch an extent as to prevent rattling of the parts While at the sametime preventing the rod being pulled upwardly when the choke isoperated.

) mentioned yo'kes 33 and 38 and through an ing and intermediate block41 and produce substantially a universal joint between the rod 32 andtubular rod 37. The purpose of this universal joint is to permit of therotary movement of the rod 17 being transmitted to the rod 32 regardlessof Whether these rods are in aligmnent or not.

In operation, the driver may conveniently reach the button 18 and pullit outwardly to operate the choke and at the same time may turn thebutton to rotate-the needle valve control rod and regulate the needlevalve as desired. Upon release of the button the spring 26 returns theparts to inoperative position.

From the above description it is thought that the construction andoperation of-my invention Will'be easily understood.
